Late one night, fostered teen Anlya Paulson plummets to her death from the overpass above San Francisco's Stockton tunnel. But did she fall or was she pushed? Pushed to find a suspect, homicide inspectors focus on naïve school teacher Greg Treadway, who volunteers as a Special Advocate for foster children. But by the time Greg's murder trial is underway, lawyer Dismas Hardy and his daughter, Rebecca, have unearthed some alternative harrowing possibilities: a missing stepfather, a roommate who ran an escort service and Anlya's own birth mother.
